MOLDING EVICE.

. To all whom it may concern:

Beit known that I, Josnrn O. RoUsHAn a citizen of the United States,residin'g atn Cedar Rapids, in the county of Linn and State of Iowa,have invented certain new and useful Improvements in Molding De-' vices,of which the following is a specification.

This invention relates to a device for molding semi-plastic substancessuch as butter or the like and has for its primary object to provide adevice for molding and compressing a given quantity of such substancesinto a solid block.

Another object of the invention is to provide a form for the moldconstructed in such a manner as to measure a certain amount of thesubstance to be molded.

A still further object of the invention is to Jrovide a mold of sim lechea and durable construction, and particularly one which is adapted foruse in connection with a table or bench.

With these and other objects in view the invention may be more readilyunderstood upon reference to the accompanying drawings which form a partof this specification.

In said drawings: Figure 1 is a side elevation of the device as appliedto a table or the like showing some of the parts in section; Fig. 2 isan end elevation on the line- 22 of Fig. 1; Fig. 3 is a detailfragmentary view of the form.

Referring to' the drawings in detail, 1 represents a frame whichcomprises an upright member and three transversely disposed arms, ofwhich the lowermost arm serves as a supporting and guiding member for athumb-screw 2 which is threaded therein and carries a spider 8 whichserves as one jaw of a table clamp. The intermediate arm 4 serves thecombined purpose of providing the other jaw of the table clamp, andcarrying the base platen 5 of the mold, which is preferably of wood andwhich is recessed at 6 to receive the intermediate arm 4 and permit thebase-platen to have a firm bearing upon the top of the table. Thetransverse arm 4 is adapted to lie flat on the top of the table inopposing and clamping pressure of the thumb screw 2, acting through thespider 3, and in holding the mold platen in place, and sustaining the reSpecification of Letters Patent. V patgnted M3 32, 1915, ApplicationmedJuly 31, 1914. Serial N 0. 854,351 if to slide within the removable form8 for pressingthe substance to be molded firmly down upon thebase-platen. This follower '7 is adapted to be forced downward by the imanually rotated pressure screw 9. The uppermost arm 10 provides theguide and support for the. pressure screw, which is threaded therein. Intransmitting and properly distributing its pressure, the pressure screw9, is connected with the top of the follower'Z, by means of a sleeve orsocket bearing 11 which carries a spider 12' at its lower end. Toprevent withdrawal of the screw 9 from the bearing 11 withoutinterfering with relative swing between them, a set screw 13, carried bythe bearing sleeve, enters an annular recess 14 in the rod 9.

Base platen 5 is constructed to not only supthe form 8 from the base 5when the mate:

rial has been molded, and pressure screw 9 has been raised.

In the practical embodiment of the invention it has been found that theplunger 7, the base 6 and the form 8 are best constructed of hard wood,the form 8 having its corners dove-tailed, nailed and glued together.

The operation is as follows: To attach the device to a table or the likethe transverse arm 41 is laid on the top of the table and the thumbscrew 2 tightened. The form 8 being placed on the base 5, the materialis placed therein and the pressure screw 9, carrying the plunger 7 isset into position and screwed up to compress the material. To remove thematerial from the form, the screw 9 is unscrewed sufiiciently to relievethe pressure; the form 8 is then raised by means of the finger lifts 15;after which the follower is further elevated and the mold block removed.A molding apparatus on, a follower cooperating with the plate clampingserew and'the intermediate arm servingithe combined purpose of opposingthe clamping screw and positioning 5 the plate jdfthe meld, saidfollower having a bearing socket for "receiving and guiding the pressure'SrW.
